The gameplay is designed to be fast and challenging, with lots of room for players to excel. Enemies are aggressive and can work together, with some of them attacking head on and others trying to flank. Their attacks are designed so that a skilled player can almost always avoid damage with quick thinking and dexterity, but messing up will get you killed fast.

The weapon customization system adds a lot of replay value, letting you play an enormous selection of distinct, viable builds. Each weapon type can be modified extensively, for example a laser can become anything from a gravity gun to an antimatter blowtorch with the right components.
